What is the use of a flotation machine? What aspects should be paid attention to when purchasing?

Flotation machine is a mechanical equipment to realize foam flotation process and separate target minerals from ores. Nearly 2 billion tons of ores in the world are processed by foam flotation process. According to rough statistics, about 90% of non-ferrous metal minerals are recovered through flotation, accounting for 50% in the field of black metal mineral separation.
The flotation machine is suitable for separating non-ferrous metals, ferrous metals, precious metals, non-metallic minerals, and chemical raw materials, and recovering useful minerals. Mainly used for separating non-ferrous metals such as copper, zinc, lead, and gold. It can also be used for rough and fine selection of ferrous and non-metallic materials.
The flotation equipment includes flotation machines and flotation auxiliary equipment (such as mixing tanks and feeders). The flotation machine is an important equipment for realizing the flotation process. During flotation, the pulp is mixed with flotation reagents and sent to the flotation machine. When the floating minerals attach to the bubbles to form a mineralized foam layer, the foam is scraped out or overflowed by the scraper to obtain foam products, while non foam products are discharged from the bottom of the cell. The technical and economic indicators of flotation are closely related to the performance of the flotation machine used.
Working principle of flotation machine: The centrifugal effect generated by the rotation of the impeller forms negative pressure. On the one hand, inhale enough air to mix with the slurry, on the other hand, stir the slurry to mix with drugs, and refine the foam at the same time, so that minerals attach to the foam and float to the slurry surface to form mineralized foam. Open the tail drain valve to adjust the liquid level, and scrape out foam with overflow or scraper.
China's mining industry is still developing rapidly, thanks to some excellent mechanical equipment. Traditional methods are too outdated, and new mechanical equipment can make up for the shortcomings and meet the needs of mining enterprises. Taking ore flotation as an example. Flotation machines can better assist people in processing production materials. Flotation machines come in different sizes and have different application scenarios.
Firstly, when purchasing a flotation machine, users should choose multiple equipment manufacturers instead of just placing an order with one manufacturer. Based on the information from these manufacturers, three reliable ones can be summarized as references for subsequent equipment procurement. How does it look reliable? Search online for information about relevant companies, and you can learn some information from the manufacturer's website. Generally, large enterprises attach great importance to publicity, and this is always true.
Secondly, targeted screening can be conducted through phone, internet, and other means. We need to clarify whether these enterprises are qualified, whether their production equipment is in place, whether customer feedback is good, and whether their after-sales service is recognized by users, etc. Through this screening, a company interested in cooperation will be identified, and the user will sign a purchase contract for flotation machines with this company.
Also, this step is crucial, requiring the manufacturer to provide a customer enterprise that is close to them, so that it is easier to investigate this customer and determine whether the flotation machine manufacturer is really that good. Then, it is necessary to conduct on-site investigations of the equipment manufacturer to see if some of the conditions within the manufacturer are the same as those advertised. Don't underestimate this aspect, as you can learn more authentic information from on-site inspections.
